Assembly type self-resetting friction energy dissipation steel frame beam-column joint with rotating center on web
The invention discloses an assembly type self-resetting friction energy dissipation steel frame beam-column joint with the rotation center on a web plate, and relates to the technical field of civil engineering anti-seismic structures. The connecting structure is suitable for being used in beam-column joints and has the advantages of being large in deformation, not prone to being blocked in the rotating process and convenient and fast to assemble. The joint comprises a column with a bracket beam, an I-shaped steel beam, a rotary friction energy dissipation structure and a pre-pressing spring reset structure. The column with the bracket beam comprises a steel column and an I-shaped steel bracket beam. A first vertical sealing plate is arranged at the first end of the I-shaped steel bracket beam; an upper arc-shaped hole, a round hole and a lower arc-shaped hole are formed in the first end of a web of the I-shaped steel beam, and the upper arc-shaped hole and the lower arc-shaped hole are symmetrically formed relative to the round hole. Three shear plate connecting holes are formed in the shear plate; three friction plate connecting holes are formed in the friction plate; the friction plate is connected with the shear plate and a web plate of the I-shaped steel beam through ring groove rivets; the pre-pressing spring reset structure can provide restoring force for the I-shaped steel beam after the I-shaped steel beam rotates.
本申请公开了一种转动中心在腹板的装配式自复位摩擦耗能钢框架梁柱节点，涉及土木工程抗震结构技术领域。适合在梁柱节点中使用，且具有变形量大、转动过程不易卡顿且组装便捷的优点。该节点包括带牛腿梁的柱子、工字钢梁、转动式摩擦耗能结构和预压弹簧复位结构；带牛腿梁的柱子包括钢柱和工字钢牛腿梁；工字钢牛腿梁的第一端设有第一竖向封板；工字钢梁的腹板的第一端设有上弧形孔、圆孔和下弧形孔，上弧形孔与下弧形孔相对于圆孔对称设置；剪切板上设有三个剪切板连接孔；摩擦板上设有三个摩擦板连接孔；摩擦板通过环槽铆钉与剪切板和工字钢梁的腹板连接；预压弹簧复位结构能够在工字钢梁转动后为工字钢梁提供回复力。
